I don't think the options available explain the plan. The second option comes the closest. I say they are going to go full speed ahead with minor tweaks to the current roster.
On offense I would try to keep the band together. Try to extend Pickens(worst case is tag him for next year) add another RB and we are set.
Defense needs lots of help obviously. Need to find out what we have with Revel, Carson, Butler and Stewart. Need to move on from Diggs. I would try to trade him before the deadline and if there are no takers, just release him. I could see him being traded to the Packers or Commanders. Maybe get a LB or Safety in return or a 4th or 5th rd draft pick.
LB needs a complete overhaul. Overshown is the only one that has shown anything and he is injury prone. They should be looking for ways to improve this unit including early draft picks.
I would like to see two new safeties. It's time to move on from the current starters.
The defensive line needs time to gel. EZE and Houston have shown a little. Fowler shows up in some games. Sam Williams is a trade candidate if anyone thinks they can turn his freak athleticism into a player.(Quinn Maybe) Kneeland and Clowney are the run stoppers but haven't shown a lot yet. DT's Clark, Thomas, and Osa are decent rotational players but still need that Dawg. Mazi is gone after this year unless someone wants to trade for him this year.
I think 7 new players would make this team incredibly improved. I would attack these positions in the draft and free agency.
2 LB's, 2 Safeties, A dog DT and Another DE on Defense.
On offense a RB to add to Williams is all that is needed.
